Tips On the TracBack Feature• Always clear your track log at the exact point thatyou want to go back to (trail head, truck, etc.).• The ‘RECORD’ option on the track log setup pagemust be set to ‘WRAP’ or ‘FILL’.• There must be at least two track log points storedin memory to create a TracBack route.• If there is not enough available memory to addmore waypoints and create a TracBack route, youwill be alerted with a ‘waypoint memory full’message, and the receiver will use any availablewaypoints to create a TracBack route with anemphasis on the track log closest to the destina-tion (the oldest track log point in memory).• If the ‘METHOD’ option on the track log setuppage is set to a time interval, the TracBack routemay not follow your exact path. (Keeping the cri-teria set to automatic will always provide themost detailed TracBack route.)• If the receiver is turned off or you lose satellitecoverage during your trip, the TracBack route willsimply draw a straight line between any pointwhere coverage was lost and where it resumed.• If the changes in direction and distance of yourtrack log are complex, 30 waypoints may not beenough to accurately mark your exact path. Thereceiver will then assign the 30 waypoints to themost significant points of your track, and simplifysegments with fewer changes in direction.• To save a TracBack route, copy route 0 to an openstorage route before activating another TracBack.Activating another TracBack or storage route willoverwrite the existing TracBack route.• Whenever a TracBack route is activated, thereceiver will automatically erase any temporarywaypoints (‘T###’) that are not contained inroutes 1-19. If there are temporary waypointsstored in routes 1-19, the receiver will create anynew temporary waypoints using the first three-digit number available. (You can also quicklydelete all temporary TracBack waypoints in mem-ory by using the ‘DELETE BY SYMBOL’ methoddescribed on pg. 19.)25The TracBack feature willnavigate your track logback to the oldest point inthe receiver’s memory.REFERENCETracBackThe track log will bedivided into segments withtemporary waypoints tocreate a route back to thebeginning of the track log.
